SMOKE CONVEYER.

Application filed December 22, 1923.

To all fr/2.0m z5 12mg/ concern.'

Be it known that I, EDWARD CHARLES LnHNnN, a citizen of the United States, and a resident of the city of Chicago, county of Cook. and State of Illinois, have invented certa-in new and useful Improvements in Smoke Conveyors, of which the following is a specification.

My invention relates to smoke conveyers and has for its object the provision of an apparatus of this kind for conveying smoke from smoke stacks or chimneys into the sewer and thus prevent the smoke from being discharged into the open air surrounding the building and becoming a nuisance; and another object is to providel means for conveying the smoke from the stack or chimney at the same time increasing the draft in said stack or chimney and thereby increasing the draft in the furnace connected thereto.

Other objects will appear hereinafter.

The invention consists in the combination and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is an elevation of a group of buildings equipped with my smoke conveyer;

Fig. 2 is an enlarged detail view of a supporting bracket, taken on line 2-2 of Fig. 4; Y

Fig. 3 is an enlarged side view, partly in section, of the suction producing means and the discharge portion of the apparatus;

Fig. 1 is an enlarged side view o-f the receiving portion of the apparatus, parts being broken away, and

Fig. 5 is a horizontal section taken on line 5-5 of Fig. 4f.

In the drawings l have shown the preferred form of my invention and in connection with a plurality of similar buildings which have smoke stacks or chimneys 11 and basements 12. The preferred construction comprises a main vertical pipe or conduit 13 extending from the ground upwards along the side to the to'p of one of the buildings 10, and a main horizontal pipe or conduit 14 connected with the top of vert-ical pipe 13 by means of curved portions 14 substantially in Y-formation. said horizontal pipe eX- tending over the tops of the adjacent buildings of said group or row of buildings, as indicated in the drawings. A branch pipe Serial No. 682,356.

or conduit 15 extends at an angle from said main horizontal pipe or conduit 14, as shown at 15. upwards along each chimney and is curved over the top thereof downward into the top or upper part of the chimney. Intake means is provided at the inner end of said pipe or conduit 15 and includes a main tubular member 16 preferably with a flaring mouth or intake port- 16, and a plurality of spaced tubular members 1"? extending laterally outward from the members 16 and curved downward at their ends having intake ports 17. The total cross section or area of these tubular members is considerably less than the interior area of the smoke stack or chimney, in order that said intake means will not stop or materially interfere with the usual and ordinary passage of smoke out of said stack or chimney whenever the device is not in active use or operation.

Suitable means is provided for supporting and retaining each branch conduit on the chimney, as best shown in Fig. 2 and preferably includes a saddle-shaped strap 18 fastened on the chimney as with members 19 for supporting the pipe or conduit 15, and a fastening strap 2O fastened to member 18 by suitable bolts or the like for firmly clamping and holding the pipe in place. Similar saddle-shaped fastening members 22 and clamping straps 23 are also used to support or retain the main conduit or pipe 14 on the top of the building, and similar suitable fastening means 24- are provided to retain the vertical pipe 13 in position at the side of the building.

A discharge conduit 25 leads from the conduit 13 into the sewer pipe 26, its lower end 25 preferably extending to the lower part of said pipe, below the surface of the liquid iowing therein, to conduct the smoke into said liquid and mir and discharge it therewith; said discharge end 25 may also be placed below the surface of other running water, as a stream or the iike, in order to mingle with said water and be carried away thereby.

Suction means 27, preferably in the form of a suction fan of any approved or wellknown construction, is interposed in said discharge conduit 25, and may be mounted upon a bracket 28 in a suitable location adjacent conduit 18, as in a small building in the yard, or in a basement. etc.; and suitable power means, preferably in the form of a motor 29 with a belt 30, is supplied to drive said suotion means Whenever it is desired to place the apparatus in operation and discharge the smoke from the smoke stack o-r chimney into the sewer;

From the foregoing disclosure it will. be seen that a very efficient and inexpensive apparatus has been provided for conveying smoke and obnoxious gases from a plurality of smoke stack-s or chimneys, `in order tol prevent the discharge thereof into the at-- mosphere surrounding said buildings, and that said. smoke and gasesy Will be mingled with the liquid in the sewer and carried. away thereby.

Vhile I have illustrated and described thel preferred form of. construction for carrying my invention into effect, this is capable. of variation and modification Without departing from the spirit of the invention.. L. therefor-eay do not Wish to be `limi-ted to the precise details of construction set forth, but desi-re to.l avail myself. of. such variation-s and modificati-'ons as come Within the scope of the appended claims..

Having described my invention, vwhat I claim. asvnevv and desire to secu-re by .Letters Patent is :4

1.- Ang apparatus of the class described comprising intake means including a tubuf.- lar y member with a mainflared intake port at itslovverend., ai plurality of spaced members extending outwardly and. downwardly from said mainmember and having downwardly opening intake portsT said members being located in the top of the chimney and being of considerably less total cross section that that of said chimney, conduit means extending from' safid intake means into flowing, Water in a conduit, and suction means'interposed in said conduit means.

2.. The combination', with a plurality of 'buildings and chimneys thereon, of a main downatth'e side of one ots-aid buildings, aV

discharge `conduit leading, freinfsaid vvertical. c'ondutt through` the basement lntoht'he lower part of a sewer conduit, and suction producing: means mounted. said` basementr and interposed in' said@ dischargel conduit.
